. .ATTACHMENT FOR GAS HEATERS' Application med my 21, 192s. serial No. 294,38?.

This invention relates generally to an attachment for gas-burning heaters, stoves and the like, but more particularly to a carbon monoxide gas eliminator therefor.

. Its chief object is the provision of a simple and efficient apparatus for decomposing and eliminating the deadly carbon'monoxide gas which usually'escapes from domestic heaters.

Another object of the invention is to prov vide a device of this character which can be readily applied to heaters of various types and which can be manufactured at a moderate cost.

In the accompanying drawings l Figure 1 is a front View of a. domestic gas vheater showing my invention in connection therewith. Figure 2`is a vertical section on line 2 2, Figure 3. Figure 3 isa transverse section on line 3 3, Figure 2.

corresponding parts throughout' the several views.

While my invention is applicable to v a- `rious heating devices from which toxic car-' "bon monoxide gas escapes, it has been shown by way of example, as applied to a domestic, radiant type gas heater 10 of ordinary construction. Fitted over the upper end of the heater to receive the products of combustion issuing from the burners thereof is a compartment on hood ll'preferably made of catalytic material, such as copper, and rising from theI upper central portion of the same is an out- Y let pipe or Hue 12 forthe passage of the prodney. This hood hasa depending rim or skirt 13 which is spaced a suitable distance from Similar characters of reference indicate ucts of combustion either into the room in' which the heater is located or into the chimfrom the heater must circulate before being discharged lfrom the flue. The hopcalite, which is a granular product composed of copper oxide and manganese dioxide, acts as a catalyst and causes any carbon monoxide present in the escaping gases to combine with the oxygen drawn through the air passage 14 and form the relatively harmless carbon dioxide. If desired, a layer of fused calcium chloride may be used in advance of the hopcalite for the purpose of absorbing any water vapor present in the escaping gases. The glass wool serves as amedium to hold the powder-like hopcalite in suspension.

Extending over the front'side of the heater and attached at its upper end to the hood-rim 13 is a catalytic apron or screen 18, also made of-copper, which acts to intercept any carbon monoxide projected forwardly from the heater and in the presence of the oxygen of the air traveling upwardly between the screen and the heater to unite therewith and form carbon dioxide.

By this improved attachment, the products'of combustion emanating'fro'm the top or front side of the heater are brought into intimate contact with catalyzing agents,

which, in the presence of the oxygen of the alr drawn into the hood 11 and into the space between the heater and the screen 18, effectively promote a union of the carbon monoxide and oxygen to formthe relatively harmless carbon dioxide gas, thereby eliminating the present objections and dangers of gas heatersand similar heating apparatusfin homes. I claim as myinvention 1. An attachment for eliminating carbon monoxide and other'poisonous gases emitted from' a heating apparatus, comprising a hood adapted to be placed over the same and having an air intake and' a discharge passage, spaced screens arranged in said passage, and a cataiyzing agentdisposed in the passage between said screens.

. 2. An attachment for eliminatingcarbon monoxide and other poisonous gases emitted from a heating apparatus, comprising a hood adapted to be placed over the same and having an air intake, a flue leading from the hood land through which the produ@ of @ambussol 'f'."tion from the heating lapparatus are discharged, screens of catalytic material ar` ranged in spaced'relation within the flue, and a charge of hopcalite contained inthe flue 5 between said screens.

' 3. An attachment for eliminating carbon monoxide from an upright gas heating apparatus, comprising` a hood adapted to be placed over the same, and a screen, of cata-2 lytic material depending from said hood and adapted to 4extend across the burner elements of said apparatus.

4. A carbon monoxideheleminator for gas heaters, comprising a hood containing an out- 15 let adapted to be placed over the heater in spaced relation thereto to provide an air intake passage, a screen of catalytic material dependin from -sa-id hood to assume a positionin ront of the burner elements of the heater, screens of catalytic material arranged in spaced relation in the hood-outlet, and a charge of hopcalite contained between said screens. f l --ff'An/attachment for eliminating carbon monoxide and other poisonous gases from flueless gas heaters, comprising a chambered member adapted to be arranged over the upper part of the heater to receive the products ofr combustion emanating therefrom, said member having an air intake and the chamber thereof containing a catalyzing agent."

' 6. A'devicefforfelinainatingLc'arbn monoxide and other poisonous gases issuing from gas heating' appliances, comprising an attachment applied to the heater and including a chamber into which theproducts of combustion issuing fromV the heater are discharged, said chamber h'aving an air inlet and containing a catalyst, the latter and the oxy- 40` gen of the air acting to. reduce the poisonous gases contained in thel products of combustion to non-poisonous gases.

7. In a gas heater of the character de scribed, the combination of a chambered member applied to the heater in spaced relation thereto to provide an air intake passage,

, and a catalyzing agent contained in the chamber of said member and with which the products of combustion andthe oxygen of the air l1.50 admitted through said passage are adapted to intimately contact.
